Penning mixture

A Penning mixture is a mixture of gases that is used in electric gas-discharge lamps. It is defined as a mixture of one inert gas with a minute amount of another gas, one that has lower ionization voltage than the main constituent. It is named after Frans Michel Penning.[1][2]

The well-known neon lighting and neon lamps and displays are filled not with pure neon, but with a Penning mixture.
